Doubts are our enemies. Self-doubt slows everything down, or even put a pause on our passion and our dream.
Don't limit yourself with your ability. Think about how to push your boundaries and achieve great work with it instead. It's more important that you keep moving forward in order to become a stronger and better person.
There must be criticism and failures along the way but don't worry, take them as word of wisdom that guide you towards what you want. Let them help you but not stopping you.
